Campcodes Grocery Sales and Inventory System SQL Injection Vulnerability

A SQL injection vulnerability has been identified in Campcodes Grocery Sales and Inventory System version 1.0. The issue arises in the file '/ajax.php?action=save_receiving', where insufficient input validation allows attackers to manipulate the 'id' parameter. This exploitation can be done remotely, leading to unauthorized database access, data modification or deletion, and potential exposure of sensitive information.

Impact

Exploitation of this vulnerability allows for SQL injection, enabling attackers to interfere with database queries. This could result in unauthorized data access, data manipulation, and in some cases, executing administrative operations on the database.

Reproduction

To reproduce this vulnerability, send a POST request to '/ajax.php?action=save_receiving' with a crafted 'id' parameter that includes malicious SQL payloads. The injection can be verified by using time-based blind SQL injection techniques, such as appending a SQL injection payload that causes a delay in the response, indicating that the injection was successful.

Remediation

It is recommended to use prepared statements and parameter binding to prevent SQL injection vulnerabilities. Additionally, input validation and filtering should be implemented to ensure that user input conforms to expected formats. Minimizing database user permissions and conducting regular security audits can also help enhance the overall security of the application.
